Boron carbide-based composite ceramic material and preparation method thereof
The invention discloses a boron carbide-based composite ceramic material and a preparation method thereof. The composite ceramic material is prepared from B4C powder, Ti3SiC2 powder and metal hydridepowder through pressure sintering. The boron carbide-based composite ceramic material which is high in density, hardness, bending strength and breaking tenacity and capable of being machined through wire cut electrical discharge machining is obtained at the low sintering temperature and the short sintering heat preservation time, the mechanical property and the machining property of boron carbideceramic are improved, and the high practical value is achieved.
本发明公开了一种碳化硼基复合陶瓷材料及其制备方法，该复合陶瓷材料由B4C粉末、Ti3SiC2粉末及金属氢化物粉末经压力烧结制备而成。本发明在较低的烧结温度和较短的烧结保温时间下，获得了高致密度、高硬度、高弯曲强度和断裂韧性、可电火花线切割加工的碳化硼基复合陶瓷材料，改善了碳化硼陶瓷的力学性能和加工性能，具有较高的实用价值。
